I have no idea what you are trying to say but we will certainly not wait for OpenMPT 2.0 to drop Windows XP support. By the time OpenMPT 1.29 gets released, Windows XP will be most likely 19 years old, making it the longest-supported Windows version in OpenMPT ever (second-longest would be Windows 98 SE with about 18 years). You need to realize that if you refuse to use a newer operating system, you will at some point also have to give up on using newer software. You will be able to continue using OpenMPT 1.28 on Windows XP if you absolutely must, but there will be no updates for the software. At least two tools that are required for building OpenMPT (Visual Studio and InnoSetup) will drop support for Windows XP in their next update, and we cannot stay on outdated tools forever just to support an absolute minority of OpenMPT users with fresh updates - at this point, there are even more Wine users than XP users.

I think it probably makes sense to drop Windows XP already in 1.29, given the InnoSetup change.

We may still continue to provide test builds for Windows XP (however I somehow question whether it is worth the (ever increasing) maintenance overhead) as test builds and .zip releases, however dropping it from the installer sounds like a good idea to not stay behind on the tools front (which always just defers migration overhead until later).
